COMBINED GAUGE WHEEL AND COLTER.

Application filed. April 19,1921. Serial No. 462,619.

This invention relates to plows, and more particularly to that type, drawn by a tractor and provided with a combined gauge wheel and colter adjustable to accommodate the varying depths at which the plow may be operated. The objects of my invention will be clearly set forth in the following specification.

.Referri-ng to the drawings, in which similar numerals indicate identical parts:

Figure 1 is a side elevation of-aplow with the combined gauge wheel and colter in position for shallow plowing.

Figure 2 is a similar view to Figure 1 with the gauge-wheel and colter adjusted for deeper plowing.

Figure -3 is av plan View of Figure 2.

Figure tis a diametrical section of the gauge wheel ,andcolter.

In the operation .of a plow provided with a gauge wheel the depth of plowing is regulated by adjustment of the gauge wheel in various ways well known in the art. Rolling colters have also been employed for the purpose of cutting, in advance of the plow, sod and surface trash to be more readily buried in the furrow as the latter is turned. I have found that the best results are obtained by combining the gauge wheel and the colter so that, by actuation of suitable mechanism, they will move simultaneously to the position desired relative to the plow body. Experiment has determined that this position is, as shown, in close proximity to the plow body where the colter aids as a resistant to side pressurev on the plow that might cause the latter to deviate from a straight line. It is also a fact that by placing the colter, as shown, in close proximity to the plow body, the eflective'operation of the colter in cutting sod and trash is materially aided not only by the suck of the plow but by the upward thrust of the earth, displaced by the plow, which tends to hold trash, such as corn stalks and weeds, against the rotary cutting edge of the colter, and,

this is particularly so in deep plowing, for it will be observed that whereas at approximately sod depth, as shown in Figure 1, the cutting action of the colter is close to the plow point, for deep plowing, as illustrated in Figure 2, the colter and gauge wheel have been adjusted rearwardly, moving in an arc eccentric to the cutting edge ,ofthe plow body, to a position productive of the best results. Part of a draft frame and a supportmg wheel 11is shown, the latter supported .on a crank axle having a vertical portion being provided in the clevis 14 for that purpose.

Abrace 18 is secured at its rear end to the beam 18 and extendsdiagonally to connection with a clevis 1 1 mounted on the draft frame 10. The clevis 14 is in lateral alinement with the clevis 14:, and is similar in construction with the latter, being provided with a vertically disposed series of holes and an adjusting screw 16*. The brace 18 is reinforced by a cross bar 18 secure: thereto and to the beam 18. A sector 21 is mounted on the frame 10 and pivotally secured on the sector is a hand lever 22 provided with a latch device adapted to engage with either of the notches 23 in the sector 21. The lever 22 is connected to the beam 18 by rods 24, 25, the former of which is pivotally attached at 26 to a standard 27 mounted at 28 on the beam 18. By a forward actuation of the lever 22 the beam 18 and attached plow body will be raised out of operation, swinging about the pivots 17 and 17 and held in the desired position by the latch on the lever engaging a notch in the sector 21. It is evident that by releasing the latch, the plow will drop ready for operation.

A casting 28 is secured on the beam 18,

intermediate the length thereof, by bolts 29 and includes a bearing for a crank axle 30 carrying upon its lower portion a combined gauge wheel and colter 31 secured in position by a collar 33 and a. washer 34 at opposite ends respectively of a hub 32, a. pin 35 holds the parts together. The gauge wheel is preferably cast with the hub and has a tread surface 35" of a desired width. A disk colter 37 is secured to the furrowward side of the gauge wheel by bolts 86, its cutting edge 38 extending beyond the gauge wheel a euliicient diet/once to ensure eliieiency in cutting.

To the end portion ot that part 0 t the cranh axle einiported in the casting 2th and extendillfl' 'liu'rowward beyond the beam 15?, it; cured. by bolts it), a clamp ell prevented from rotary movement on the axle by a key 39. An arm 42 extends from the clamp all and a love ilil secured thereto by rivets ii the lever all is provided with a latch adapted to engage with any one of notches to in a sector l6 mounted on the beam 18 and fixed thereon by bolts 29 and 457.

Both of the levers .273 and -l'-l are convenient to an ope 'ator on the frame 10, lever 22 operable to raise the plow from the ground irrespective oi. the position of the gauge wheel and eolter, and lever ll operable to adjust the combined gauge wheel and colter not only to regulate the depth oi? plowing but to present the colter, relative to the plow body, to cut the sod that may be in its path, in the most ell'ective manner.

hat I claim is-- 1. In a plow including; a beam and a plow body carried therebv, the combination therewith of a crank axle rockably journaled on the beam and having a epindle at its free end, a combined gauge wheel and colter supported on said spindle, a lever secured on the es-3a,:

as' V. and operative to 'luClL said axle and swing the gauge wheel and colter upwardly and rearwardly oi? the point of the plow body in an arc eccentric to the vertical cutting edge ot the plow body.

2. In a plow including, a beam and a plow body carried thereby, the C(Hl'lllllltltlOll therewith ot a crank axle jonrnaled on the beam ii'orwardlv ot the point of the plow body, and having a spindle at its free end, a combined gauge wheel and colter supported on said spindle, and a lever operative to rock Paid axle and swing the gauge wheel and colter in an arc eccentric to the vertical cutting edge oi? the plow body and rearward of the point of the plow body.

In a plow including a beam and a plow body carried thereby, the (IOlllblllEltlOll therewith of a crank axle jonri'ialed on the bean] :lorwardly of the point of the plow body and having a spindle at its tree end, acombined graueje wheel and colter supported on said spindle, a lever operative to rock said axle and swing the gauge wheel and colter npwardly and rearwardly ol the point ot the v plow bod in an arc eccentric to the vertical cutting edge of the plow body, and means to hold said gauge wheel and colter at varying points in its arcuate movement.
